Is BCAA halal?

BCAAs are leucine, isoleucine and valine. Industrial material is usually fermented; a minority of cheap amino acids have been made from keratin (hair, duck feathers). Instantised powders may carry lecithin or flavour carriers.

UnverifiedNot enough reliable source evidence to classify

Fermentation vs keratin is the live split. No class ruling cited. Insufficient-evidence, not haram-by-default.

The detail

Hair-derived amino acids are a documented industry issue, not a rumour. Most branded BCAA today is fermentation. Instantised (water-soluble) versions often add sunflower or soy lecithin and a flavour system — those are separate rows. Capsules re-open gelatin.
